The Laboratory studies physiological, biophysical and biochemical processes of a living organism under effects of various technogenic factors, including ionizing and non-ionizing radiation, in order to discover the ways of how to raise its radioresistance and adaptive capacities.

The main direction of research is focused on developing in vivo biological models using laboratory animals to study radiation and non-radiation effects on cellular and sub-cellular elements, and understand the mechanisms of malformations in pathological conditions of different genesis.

To achieve the set goals, the lab researchers:

carry out experiments using in vivo and in vitro models to study radiation-induced pathologies;
study spontaneous and induced carcinogenesis in biological models exposed to ionizing radiation;
study molecular-cellular radiosensitivity mechanisms of biological systems;
search for the novel medicinal substances possessing radiomodifying properties;
study the process of the body’s adaptive capacity formation under chronic exposure to low-intensity electromagnetic radiation from wireless devices (e.g. mobile phones, Wi-Fi routers etc.);
study nanomechanical properties of cells in various pathophysiological processes;
investigate the structural and mechanical properties of nanoparticles in biological liquids (e.g. extracellular vesicles, lipoproteins etc.).

History

The Laboratory of BioSystems Sustainability was founded in 2020 by merging together three other labs, i.e. Laboratory of Experimental Biological Models, Endocrinology & Biochemistry Laboratory and Combined Effects Laboratory.

Endocrinology & Biochemistry Laboratory was founded in 2003 by combining four laboratories – Biochemistry, Physiology, Endocrinology, Morphology and Cytogenetics, which had been functioning before IRB permanently moved from Minsk to Gomel. The laboratory’s founder and long-time ruler in the first five years of its functioning was Academician of the National Academy of Sciences of Belarus, Honoured Scientist of the Republic of Belarus, Professor, Doctor of Medical Sciences Evgenij F. Konoplya. From 2009 to 2015, it was headed by Doctor of Biological Sciences, associate professor Alexander D. Naumov. In 2004 – 2015, the lab’s deputy head was lead researcher Gennadii G. Vereshchako, Candidate of Biological Sciences. The last head of the laboratory, from 2017 to 2020, was Grigoriy A. Gorokh.

laboratory for the development of nuclear-physical analysis methods and their application in biology and medicine, which was later transformed into laboratory of radioecology headed by Dr. A. Malenichenko. In 1992, following institutional rearrangements at the Institute of Nuclear Energy, the laboratory was reorganized into laboratory of radiation and toxicological ecology and became part of the Institute of Radioecological Problems of the National Academy of Sciences of Belarus. In 2003, the Institute of Radioecological Problems was reorganized and the laboratory became affiliated to the Institute of Radiobiology of the National Academy of Sciences of Belarus, which was soon after relocated from Minsk to Gomel.

The origin of Combined Effects Laboratory dates back to 1992 when it was established following institutional rearrangements taking place at the Institute of Nuclear Energy and creation of the Institute of Radioecological Problems of the National Academy of Sciences of Belarus. At that time, the lab was headed by Dr. A.F. Malenchenko and renamed into laboratory of radiation and toxicological ecology. In 2003, the Institute of Radioecological Problems was reorganized and the laboratory became affiliated to the Institute of Radiobiology of the National Academy of Sciences of Belarus, which was soon after relocated from Minsk to Gomel.

Laboratory of Experimental Biological Models was created in September 2014 and up until 2017 was headed by Dr. T.I. Milevich. The lab’s Radiation Exposure Sector was operating two gamma-radiation units, IGUR and GAMMARID, used for acute and chronic irradiation of biological objects. The outstanding work done by the unit operators over many years can be found reflected in quite a number of PhD and Doctoral theses authored by the home and external researchers.

Research Areas Today

The lab’s current research efforts fully match with the national priority directions with regards to scientific, technological and innovative activities set by the Government for the period 2021–2025, being as follows:

the use of atomic force and fluorescent microscopy techniques to study structural and mechanical properties of the cellular surface layer, post-cellular structures and nano-scale organic and inorganic objects for the purposes of developing fundamental principles of innovative diagnostic approaches aimed at determining pathological conditions of a body at cellular and sub-cellular levels, and deepening our understanding of the pathogenesis of different health disorders, including radiation-induced pathologies;
development of prognostic tests for the assessment of clinical radiation effects of radiotherapy;
simulation of radiation-induced pathologies and validation of elaborated methods for their correction using laboratory animals;

The Department’s Laboratory Equipment

In 2019, within the framework of Gratuitous Aid Agreement between Mission Support and Test Services, LLC (USA) and IRB, the laboratory equipment was essentially reinforced with an X-ray biological irradiation unit X-RAD 320, a self-contained X-ray system designed to deliver a precise radiation dosage to biological samples and small laboratory animals.

The X-RAD 320 unit offers the ability to experiment either with irradiation of the whole animal body or its specific parts and areas. Irradiation of cell cultures and suspensions in experiments in vitro is another advantageous ability of this instrument.

It is equipped with a built-in OptiMAX imaging module used in the variety of radiation therapy research and producing high-resolution optical molecular and X-ray images.

This unit is a perfect use for the variety of research purposes, from modelling ionizing radiation-induced pathologies and studying the mechanisms and effects of ionizing radiation at different organizational levels of biological systems to working out the ways of correction of somatic and cancerous diseases and evaluating remedial effects from different medicinal substances and materials.

The atom-force microscope AFM BioScope Resolve and an inverted fluorescence microscope Axio Observer 3 provides with a high-resolution examination of structural, mechanical and other cell properties, live cells in liquid media, nanoparticles etc.

Compact multi-purpose benchtop laboratory centrifuges

The Cytomics FC 500 Flow Cytometry System (Beckman Coulter, USA) performs an automated 5-color analysis using a single argon-ion laser with a wave length of 488 nm, and, with being able to analyze more antibodies per tube (e.g. immunophenotyping of blood lymphocytes), examine the ongoing changes in dispersed tissues (e.g. testicular tissue) and its other features, maximizing the method’s informative value and a workflow efficiency.

Cell culture equipment:

laminar-flow hood, CO₂ incubator and inverted microscope

These pieces of equipment are used for microbiological, biomolecular, and cell (tissue, organ) culture research.

Particular attention is being paid to the use of high-efficiency liquid chromatography for the separation and purification of complex biological mixtures.

The Department’s research in this field is backed up by the Agilent 1100 Series Liquid Chromatograph, which helps to determine the concentrations of biogenic amines in different parts of the brain, as well as the steroid hormones in adrenal glands and blood serum.
